Write an equation that illustrates a common error students make when applying the commutative property.

Step-by-step explanation:

The commutative property rule states that the order in which we multiply numbers does not change the outcome/ result

for example

3*4=4*3

proof

3*4=12

4*3=12

But sometimes students may apply this rule to division and subtraction which is a mistake

e.g

2/3=3/2wrong

2-1=1-2wrong

answer:   rlly

step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
